BILOBE OR MULTILOBE TANK

The bilobe or multilobe tank (1) for storing liquefied natural gas comprises at least two tank sections (1a, b, 1c, 1d, 1e), each tank section (1a, 1b, 1c, 1d, 1e) having a curved upper surface and curved bottom surface, the tank sections (1a, 1b, 1c, 1d, 1e) being joined to each other so that the tank (1) has an undulating upper surface (12) and an undulating lower surface (11). Each tank section(1a, 1b, 1c, 1d, 1e) is connect- ed to an adjacent tank section (1a, 1b, 1c, 1d, 1e) with at least one horizontal connecting duct (17, 18) so that a horizontal flow path is formed between the lower-most points (13) of the adjacent tank sections (1a, 1b, c, 1d, 1e) or between the uppermost points (16) of the adjacent tank sections (1a, 1b, 1c, 1d, 1e). 种用于存储液化天然气的双叶或多叶储罐(1)包括至少两个储罐区段(1a，1b，1c，1d，1e)，每个储罐区段(1a，1b，1c，1d，1e)均具有弯曲上表面和弯曲底表面，所述储罐区段(1a，1b，1c，1d，1e)被接合至彼此，使得所述储罐(1)具有起伏上表面(12)和起伏下表面(11)。每个储罐区段(1a，1b，1c，1d，1e)均利用至少个水平连接管道(17，18)连接至相邻的储罐区段(1a，1b，1c，1d，1e)，从而在相邻的储罐区段(1a，1b，1c，1d，1e)的最低点(13)之间或者在相邻的储罐区段(1a，1b，1c，1
